The supervisor of the Samaritan Emergency Department, Dr. O’Neill is a conscientious and principled doctor who operates strictly by the book and expects others to do the same. Her careful watch over the ED only further complicates John’s situation, but as tightly wound and emotionally reserved, as she may seem, Dr. O’Neill isn’t entirely without compassion. Despite her insistence on maintaining clinical distance and her growing suspicions about John’s competency, she can’t quite shake her loyalty to, or concern for, her longtime coworker and friend.
